Be it known that i', WrnLrAtrFnuDnsrcu Diego, Siate ot @alitornia-,haveinvented a new and nseini Adj estable itietai Basin-Plug,

of which the following is a specieation, ref' @rence being had to theaccompanying draw ings. I

,My invention relates `to improvements in metal basinepiugs; andtheobjects of my improvements are lto provide a convenient and thoroughmethod of cleaning and removing sediment audaccumuiations from theoutlet.

of the-basi'mrwhich i accomplish by means of a removahleand adjustablecombination strainer and overtiow cut-n, and to provide a safe4andiconvenient method of making wa` ter-tight connection between theplug and the basin,v which I accomplish by making the basin-plug in twosections and. by means of concave lock-nut.

n In the drawings, Figure lI is an elevation showing in section theentire ping and a por- Fig. 2 is a view ot the combination strainer andoverow cut-0E as it 'appears when removed from the basin-plug,

and Fig. 3 is an elevation showing in section the upper' portion of thebasin-ping with the strainer and cverilow cuto removed.

Similar letters refer to similar parts throughout the several views.

My adjustable basin-plugin made up of two principal parts A and E, thesebeing connected by means of a heavy scheer-thread a and being adapted.to be inserted from opposite directions through the dischargempening inthe basin H.y 0n the upper portion of part B is a concave lock-nutfb,lay/means of which a thoroughly water-tight connection is made with thebasin. This nut being concave has a tendency to draw the rubber gasketc, Fig. 1, firmly against the basin-plug, thus preventing any leakage,whereas a flat-surfaced nut almost invariably causes the gasket tospread away from the ping, making it dinicult to eect a water-tightjoint. For this reason I prefer to use a concaved nut; but that aflat-surfaced nut may be used, if desired, without departing from theprinciple of my invention.

i Having the basin-plug in two parten. and

being often crackedin the operation.

B and made up with a lock-uut b, it becomes possible to use the plug iuconnection with eithena lead trap or a brass trap, audit also does awaywithpthe strain on the basin, which is invariable when au old-style plugis being made up, and. all danger of cracking the basin or of twstiugthe strainer in the plug is eliminated. A l

' In making the connection with my plug the `part B is'iirst connectedwith the trap, then theI basin; is allowed to rest on the lock-nut, andthen the" part A is connected to the part B from the top by thethresda.. All that then-remains to be donei's 'to make theconnoction'tight by, screwing up the nut b. As the part B isalreadyattached to the trap, thus making Vit impossible for the plug to twist,it is evident that all strain on the basin is 'eliminated. 1 In making aconnection with-an oldstyle plug the connection is first made with thebasin, the connection with the lead trap then being made by aunion-joint. In making this unin-joint a considerable strain isnecessarily thrown on the part of the plug whichis connected with thebasin, the basin In attempting to'relievc the basin of this strain it isnot unusual for a iile or other similar article to 'be inserted in rthecross-pieces which form the strainer of the plug, with the com- 'wherean old-style 'part B is employed unprovided with my lock-nut b I avoidstrain upon the basin by removing the strainertube when setting up thebasin, thus enabling me to insert a plug of wood into the basin-plug farenough to get a purchase suicient to make the joint tight, after whichthe strainer may he replaced. 1

The removable and adj ustablc combination strainer and overflow cut-off,Fig. 2, is in the form of a tube, which fits into'the upper part of thebasin-plug and rests on the shoulder' d, Fig. 1, and may be made tightby a ground joint. Within the tube is the strainer e, (shown clearly inFig. 2,) while through the side of the tube is cut a hole e, of suitablesize, so situated as to register with the opening f, through which waterfrom the overflow-pipe Genters through the upper portion ofthe plug A tothe interior ot the waste-pipe B. This strainer and overl-low cubed' canbe easily removed from the basin-plug with the fingers, thus providingan easy and satisfactory means of removing ordinary obstructions fromthe plug or pipe Without the assistance of ai plumber and doing awaywith the necessity of gouging the same down and eventually filling thepipe, asis very often the ease when a nonremovable strainer` is used. Mycombination strainer and overflow cutfo can also he easily adjusted withthe fingers, so as to close the oblong slotf, through which the waterwhich has passed through the overflow-holes g of the basin enters thewaste-pipe, thus cutting off back pressure, which would otherwise resultthrough the overflow-pipe when the wastevpipe is being cleared by meansof a forcepump or other pressure appliance. This isl accomplished bysimply turning the Strainer and overow. cut-*off one-fourth around, sothat the slotfis closed, as shown in Fig. l, and this not (only permitsthe use of a greater pressure in clearing the waste-pipe and preventsany of lthe foul and greasy sediment that accumulates in the wastepipefrom being forced into the overflow-passage G of the basin, from whichplace-it cannot be thoroughly removed, but also makes itl entirelypracticable for one man to attend to the inat-` ter. Under the presentmethod of placingy the hands over the overfiow-iulet g' near the, top'ofthe basin in order to obtain a pressure made necessary by the absence ofmy adjust-V able overiiow cut-off not only is it diicult to: obtain muchpressure, but the services of twoj men are necessary.

I claire--A V 1. In combination with a basin having a .dischargeopening,a basin-plug` provided with inserted in the opening fromopposite sides thereof and to engage each other therein, and twoflanges, one ou each tube, arranged on opposite sides of the basin, oneof the flanges being adjustable in position on its tube toward and fromthe other flange and arranged to clamp the basin therebetpeen.

3. The combination withf'a basin having a discharge-opening, abasin-plug therein, and an overiioW-passage from the basin leadingthereto, of an adjustable plug fitting within the basin-plug, andadapted to close the overflow-passage, said inner plug having an openingin .its side whereby by rotation of the plug the overow-passage may beopened.

4f. The combination with a basin having a discharge-opening, a basinplugtherein and an overflow-passage from the basin leading thereto, of aremovable plug fitting within the basin-plug, said removable plug beingproviderhwith a strainer and having walls adaptedto-ciose theoverfiow-passnge and having at one side an opening therethrough whereby,by rotating the removableplug, the overliow-passage may be opened.
